Intra-prediction according to virtual boundaries for video coding

Abstract:

An example device for coding (encoding or decoding) video data includes a memory configured to store video data; and one or more processors implemented in circuitry and configured to: code data representing a location of a virtual boundary defining a clean side of a picture of video data and a dirty side of the picture; disable use of blocks on the dirty side for intra-prediction reference of blocks on the clean side; and code the picture without using the blocks on the dirty side for intra-prediction reference of the blocks on the clean side.
